Aside from some diners, very few independently owned restaurants remain open 24 hours a day, simply because it’s expensive to keep employees working through the night when there very well might be no customers to serve.
But chain restaurants generally have deeper pockets than independent ones, so some of them go above and beyond the call of duty and remain open around the clock.
SORCE will also provide the measurements of the solar spectral irradiance from 1nm to 2000nm, accounting for 95% of the spectral contribution to TSI. Everyone is agreed: SORCE provides precise state-of-the-art measurements of TSI. The SORCE scientists very helpfully provide graphs of their mission data online: However, there is a problem. Very helpfully Wikipedia included a graph of Extraterrestrial Total Solar Irradiance. It launched into a 645 km, 40 degree orbit and is operated by the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado (CU) in Boulder, Colorado, USA. Everything if you are trying to precisely measure TSI. Because the SORCE satellite isn’t above the Earth’s atmosphere! Let’s start with Hydrogen doing something naughty in the geocorona.
The effective temperature, or black body temperature, of the Sun (5777 K) is the temperature a black body of the same size must have to yield the same total emissive power. The Sun’s Photosphere has an effective temperature of 5,778 K. Climatologists will immediately wave their hands and say this is pure nonsense. SORCE is orbiting about 90,000 kilometres below the top of the Earth’s atmosphere. Still think we can just disregard the atmosphere above 645 kilometres? Hydrogen emits X-Rays in the geocorona after colliding with Solar Wind ions: The geocoronal X-rays are caused by collisions of heavy ions of carbon, oxygen and neon in the solar wind with hydrogen atoms located tens of thousands of miles above the surface of Earth.
The problem with Total Solar Irradiance [TSI] is two fold: Firstly: Scientists aren’t Climatologists. The current generation of measurements come from the state-of-the-art satellite mission called the Solar Radiation and Climate Experiment [SORCE]: The Solar Radiation and Climate Experiment (SORCE) is a NASA-sponsored satellite mission that provides state-of-the-art measurements of incoming X-ray, ultraviolet, visible, near-infrared, and total solar radiation. SORCE measures the Sun’s output with the use of state-of-the-art radiometers, spectrometers, photodiodes, detectors, and bolometers engineered into instruments mounted on a satellite observatory.
